If we would know. what it is, we would change it. But, currently it is a 
ghost on some computers only. ;-)

Yes. The middle field says, when you have last set adjustment.
It's the count of seconds since 1/1/1970:

     TZ= LANG= date --date="1970-01-01 +1162000000sec"
     Sat Oct 28 01:46:40 UTC 2006

Have tested co_div64 against the div64_32 by simulate timediffs between 
5 to 10*3579545, and have compaired the jiffies result and remainder for 
every timediff. Results are all exactly the same.

See attched file.
The output under Windows is the same as under Linux 32 bit:
     co_div64: 15 f
     co_div64: 983055 f000f
     div64_32: 16 10, rem:0 0
     div64_32: 1048576 100000, rem:0 0
     done
